UNITED STATES PATENT of rom JAMES J. HINDE, F SANDUSKY, OHIO.

MACHINE FOR MAKING PAPER-BOARD.

Specification of Letters Patent.

Application filed February 19, 1910, Serial No. 544,888

To all whom it may concern."

Be it known that I, JAMES J. HINDE, a

citizen of the United States of America, re-

siding at Sandusky, in the county of Erie and State of Ohio, have invented certain new and useful Improvements in Machines for Making Paper-Board, of which the following is a specification, reference being therein to the accompanying drawings.

The invention relates to the manufacture I of paper or pulp board composed of a plurality of sheets glued to each other, and

more particularly to the manufacture of board in which a corrugated sheet is affixed to plain sheet facings.

It is one of the objects of the present invention to facilitate the drying of the board to increase the setting of the glue or other adhesive material and to increase the output.

To this end, the invention consists in the means employed for engaging the glued paper sheets and for drying the same, and,

further, in the peculiar construction, ar-

rangement and combination of parts as hereinafter set forth.

In the drawlngs, the machine is repre-' sented diagrammatically in vertical longitudinal section. x

A is a roll of paper from which a strip is fed over a series of corrugated rolls B B B to form a crimped orcorrugated strip C. This strip is then fed over glue-applying rolls D and E, which apply the adhesive material to the tips ofthe corrugations on opposite sides of the strip.

F and G are rolls of paper from which.

strips Hand I are'fed parallel and adjacent to the corrugated strip after the latter has passed engagement with the. gluing devices.

The strips H, I and C are thus fed into.

parallelism, and are pressed into contact with each other by passing between parallelly-arranged conveyor belts J J. These belts are preferably formedof felt or other flexibleporous and absorbent materia-L-and they are guided by passing around rolls -K K', and thence to warming drums L L, the latter being heated by suitable means,

such as steam.

In the operation of the machine, the drums L L and rolls K K are driven by suitable mechanism (not shown) to propel the belts J J at the desired speed, which is the same as that at which the corrugated strip C is delivered from the crimping rolls and the glue-applying devices. Thus, the

corrugated strip will be fed in between the plainfacing strips H and I on opposite sides thereof, and will be pressed in contact therewith by. the parallel portions of the belts J J. These belts being of. a porous absorbent material, which is heated from contact Patented Oct. 17, 1911. i

with the hot rolls L I1, will absorb the moisture from the paper strip passing therebetween and will cause the settin of the glue. Thus the material as it is delivered consists of a corrugated or crimped center,

which is firmly united with the facing strip,

in pressing the united sheets in contact with a heated surface of absorbent material to extract the moisture and set the glue.

2. The combination with means for delivering freshly glued multi-ply paper or pulp board, or parallelly-arranged traveling surfaces of absorbent material between which said board is passed, for the purpose de-' scribed.

3. The combination with means for deliv- I ering freshly glued aper or pulp board, of an endless belt of a sorbent material hav mg a portion thereof held in contact with the board, and means operating upon the return portion of said belt for extracting the moisture therefrom.

' 4. The combination with means for delivering freshly glued paper or pulp board, of y a pair of endless belts of absorbent material having'parallelly-arranged portions between and in contact with which thepaper board 1s fed, and means: for extracting the moisture from said belts.

5 The combination of a pair of endless belts'having parallelly-arranged portions, of

means for delivering a plurality of paper strips betvgyeen said belts, one or more of having freshly glued surfaces.
